Sound Level Meter dengan fungsi penyimpanan data ( Data Logger)

Data bisa diolah di komputer sesuai kebutuhan

Mudah dipakai dan praktis

This Digital Sound Level Meter is an instrument to measure Sound Pressure Level in decibels (dB).

This meter is featured with wide measuring range (30 ~ 130 dB), Bar-Graph Indication, A/C frequency weighting, Fast / Slow response and Maximum Hold function.

Moreover, the meter can connect to PC for Data Logging with optional USB cable.

This is a portable, easy to use and handy instrument for sound quality control in office, home, school and construction site. The meter has wide range of applications such as noise pollution studies, research and other industrial use.
